I used Online Paint Boards aka Oekaki Boards, when I was younger, and I enjoyed them.
It would be really cool if Decentraland had a painting application where others can watch you live on a small 500x500 pixel (or larger) shared painting canvas or screen. Ultimately I think it would be really interesting to have this option, and be able to create and sell ART NFT made inside Decentraland. I had a dream yesterday that my child was attending artschool through this world, and I had to share it.
I think it also would be cool to have the option to have up to 3 users able to use the same project/canvas to collaborate with the art project. Does anyone think this would be a useful application or even a possible one for Decentraland?
